Cao Manh Dat updated LUCENE-7442:
---------------------------------
Attachment: LUCENE-7442.patch
It seem that TestRandomChains init MinHashFilter with wrong parameters
{code}
public MinHashFilter(TokenStream input, int hashCount, int bucketCount, int
hashSetSize, boolean withRotation)
{code}
hashCount, bucketCount, hashSetSize must be positive ones.
Here are the patch to fix this issue.
> MinHashFilter.FixedSizeTreeSet.add() calls TreeSet.last() without first
> testing for emptiness, under which condition NoSuchElementException is thrown
